Under the production mode taking orders as driving force, the method is suitable for optimizing the production line distribution aspect of spinning enterprises with relatively shaped equipment, and improves the production efficiency by adjusting the production line distribution of different orders.
According to the production scheduling plan optimization method based on the genetic algorithm, the specific application environment and related parameters are changed, as shown in fig. 2, the method comprises the following steps:
s1: analyzing the detailed project requirements of the production plan scheduling optimization;
on the premise that the production task of a textile enterprise is based on an order, the detailed project requirements refer to: the content of the order is determined, batch information is defined according to the order, and process influencing factors of the workpiece are defined according to parameters of production equipment in a production workshop, so that the process from the order to model building can be smoothly realized.
Batch: when textile enterprises receive different orders in a short time, different textile in the orders are split into batches, and the batches in the different orders are produced in a unified mode. The method defines a textile in an order as a "batch". For example: the enterprise receives three orders in a short period of time, with order one containing A, B, C three types of textiles, order two containing A, C two textiles, and order three containing B, C two. Then, the production plan contains a total of 7 batches.
In summary, when a textile enterprise receives different orders in a short time, the processing requirements of the orders are split into batches, and the batches are produced respectively.
S2: converting model parameters;
when the model is established, a mathematical language is needed, and according to the description of the detailed project requirements, the specific mathematical language is described as follows:
among the orders received by the enterprise, there are i kinds of yarn fabrics (spun yarns) which are produced in i batches, the total amount of each batch being NiThe total amount is based on the final output of the spinning frame.
The method comprises the following steps of sequentially carrying out seven working procedures on different batches of i textiles, namely blowing-carding-drawing, pre-drawing, sliver-doubling and rolling, combing, final drawing, roving and spun yarn which are sequentially produced.
In an operation embodiment, for example, if a new order exists, a variety, a required weight and a finishing date are input according to the content of the order, for example, two types of textiles exist in the new order, the first type is the variety A, the weight is 15 tons, and the finishing date is 12 months and 10 days in XX year; the second is variety B, weighing 10 tons, ending at 12 months and 20 days XX years.
The two scrims were produced in two batches, the total amount of which was 25 tons. Both batches of textiles are processed through seven sequential processes.
S3: constructing a model adopting a genetic algorithm;
a model using a genetic algorithm is constructed, and the scheduling aims to minimize the maximum completion time.
Process influencing factors need to be considered at this time: the influencing factors comprise the manufacturing rate of each process, the running rate of equipment, the running time of the equipment, a machine production parameter configuration table and the dry and wet weight of a produced product. And then the number of the factory equipment and various parameter information need to be input so as to determine constraint conditions, wherein the constraint conditions comprise process constraint, machine constraint, completion time constraint and the like.
Therefore, in operation, the number of plant devices and various parameter information are also required to be recorded and stored in a relevant table, and the information includes the following contents:
(1) a factory machine number configuration table;

(3) the manufacturing rate of each procedure-equipment operation rate-equipment operation time table;
(4) a machine production parameter configuration table;
(5) the dry and wet weight of the product is g-m;
(6) each process switches the product-required schedule.
Therefore, the constraint conditions are determined through data interaction, and the optimal scheme can be generated by utilizing an algorithm subsequently.
Based on the above analysis, the following mathematical optimization model was constructed:
an objective function:

f is the minimum maximum completion time, m is the number of batches, i is the ith batch, CiIs the completion time of the ith lot.
Constraint conditions are as follows:

(2) And (3) machine constraint: in the same production line, only after the previous batch is processed, the next batch can be processed.
C(i+1)jk-Cijk-P(i+1)jk≥0(X(i+1)jk+Xijk<=1)
(5) And (4) completing time constraint:
Cij(k+1)=max{Cijk,STij(k+1)}+Pi2(k+1)
wherein, the ith batch is on the jth production line, and the time C _ (ij (k +1)) for completing the (k +1) th process satisfies the following constraint:
Cij(k+1)=STijk+Pij(k+1)
wherein, CiFor the completion time of the ith lot, CijkIndicates the end time, P, of the kth process step when the ith lot is produced on the jth production lineijkIndicates the processing time of the kth process in the production of the ith lot on the jth production line, STijkIndicating the start time of the kth process when the ith batch is produced on the jth production line.
Figure BDA0002541183470000071
(4) At the start of the process, all the textile material is ready;
(5) each batch was processed sequentially in the order of 7 passes, and only once.
When the method is used for the first time aiming at an order, the quantity of factory equipment and various parameter information need to be input, and the more the relevant information is, the more the information is, the more clear the process constraint, the machine constraint and the completion time constraint can be judged. In the subsequent order processing, the previously entered information can be directly used, and if the information needs to be adjusted, subsequent operations are performed after the adjustment.
